So it’s a Systema TW5 system. It been sent to England to be overhauled by Tackleberry (so motor, HopUp, and barrel). It has a KAC front rail system on it. The real reload system has been disabled due to how weak the front bolt is on the TW5. The gun has also been disabled so it fires on semi. Stampede Airsoft went through the gun to replaced the spring (350fps),hopup nub, and bucking. Basically just an overhaul to make sure everything was running fine. This is a steal of a deal. Serious inquiries only, price is firm, no trades. Buyer pays shipping and PPF.
